Special offer 10% off:  when returning your current PST Serial Response Box, you will get a 10% discount on the new Chronos Box, offering much more features than the old SR Box. Use coupon code Chronos2018.

The Chronos Box is a powerful new USB-based response and stimulus device for accurate collection and verification of tactile, auditory, visual, and analog response timing along with the precise source of audio and generic analog output timing. Chronos features sub-millisecond accuracy and consistent sound output latencies across machines. The Chronos Box includes 16 digital inputs and 16 digital outputs, eliminating the need for a parallel port. All responses collected are synchronous to the E-Prime® time domain. Multiple Chronos devices can be connected to a single PC.


The Chronos system includes a Microphone and Photo Sensor
.

chronos_photosensorThe Photo Sensor can be used on CRT, LCD, and projection displays to detect stimulus onset events, refreshes, and measure rise and fall times. The Photo Sensor accessory (included) can be used on CRT, LCD, and projection displays to detect stimulus onset events, refreshes, and measure rise and fall times. All responses collected are synchronous to the E-Prime® time domain.
The Chronos graphical user interface allows for user-friendly implementation of the system’s wide range of features.

The Chronos Box also introduces a large set of Task Events to facilitate the design of basic to complex experiments without the use of script (E-Prime 2.0 Professional).
